Abstract: L'invention concerne un fluide caloporteur non aqueux à base d'alcool polyhydrique à toxicité réduite, comprenant au moins un alcool polyhydrique qui agit comme un inhibiteur d'enzyme ADH, tel que par exemple un propylène glycol, ce qui permet de réduire la toxicité d'un éthylène glycol, le cas échéant. Ledit fluide caloporteur peut également comprendre des inhibiteurs de corrosion solubles dans les alcools polyhydriques utilisés par ledit fluide caloporteur. On peut utiliser ce fluide caloporteur comme réfrigérant pour des moteurs à combustion interne tels que des moteurs d'automobiles ou pour des composants électriques ou électroniques; et comme fluide caloporteur pour des systèmes de chauffage par énergie solaire ou pour maintenir des températures dans des processus industriels. L'invention concerne également un fluide de préparation à faible toxicité destiné à absorber l'eau provenant de systèmes d'échange thermique avant l'installation du fluide caloporteur comprenant un éthylène glycol et au moins un alcool polyhydrique, notamment un propylène glycol agissant comme un inhibiteur d'enzyme ADH.
Patent CA-2454111-A1 (CA)
Inventor: ANDERSON ROBERT J
IPC: H04W4/90
Filed: 2002-07-15
Abstract: In an overlay Wireless Location System, an Abis interface is monitored to obtain information used to locate GSM phones (S116). Signaling links of the Abis interface are passively monitored to obtain certain information, such as control and traffic channel assignment, called number, and mobile identification, which is not available from the GSM air interface of the reverse channel (S110-S116). This approach also applies to IDEN and can be broadened to include CDMA systems where the GSM architecture has been used and the system includes a separated BTS to BSC interface.

Title: Method for providing cardless payment
Inventor: HIRKA JEFFREY L
IPC: G06Q20/00
Filed: 2002-09-20
Abstract: The method and system of the invention provide a variety of techniques for using a selected alias and a selected personal identification entry (PIE) in conjunction with use of a transaction card, such as a credit card, debit car d or stored value card, for example. A suitable number or other identification parameter is selected by the account-holder as an alias. The account-holder is then required to choose a PIE for security purposes. The alias is linked to the account-holder's credit card number via a database. When the account- holder enters into a transaction with a merchant, the physical card need not be present. The account-holder simply provides his or her alias and then the PIE. This can be done at any point of sale such as a store, catalog telephon e order, or over the Internet. The alias and PIE are entered and authorization is returned from the credit card company.

Inventor: BOTHNER RONALD E
IPC: G01V5/10
Filed: 2002-03-20
Abstract: A well logging tool (10) has a neutron source (16) for irradiating formation surrounding a borehole. Two detectors (20,22) are mounted in a spaced-apart vertical relationship within the tool pressure-resistant housing (12). Each detector detects capture gamma radiation across the entire gamma ray energy spectrum, windows are set in this spectrum to separate two distinct energy ranges, thereby generating a total of four independent sets of signals, two for each detector. One set of signals is indicative of the hydrogen content and insensitive to the chlorine content of the irradiated formation. The second set of signals is indicative of the hydrogen plus the chlorine content of the irradiated formation. By comparing the sets of signals in two proportional energy ranges, the logging tool allows to generate a log that helps determine the presence or absence of hydrocarbon or salt water in the formation.

Title: Antigen-presenting cell populations and their use as reagents for enhancing or reducing immune tolerance
Inventor: MUNN DAVID
IPC: A01N63/00
Filed: 2002-04-12
Abstract: The present invention is based on the discovery antigen-presenting cells (APCs) may be generated to have predetermined levels of expression of the intracellular enzyme, indoleamine 2,3-dioxygenase (IDO). Because expression of high levels of IDO is correlated with a reduced ability to stimulate T cell responses and an enhanced ability to induce immunologic tolerance, APCs having high levels of IDO may be used to increase tolerance in the immune system, as for example in transplant therapy or treatment of autoimmune disorders. For example, APCs having high levels of IDO, and expressing or loaded with at least one antigen from a donor tissue may be used to increase tolerance of the recipient to the donor's tissue. Alternatively, APCs having reduced levels of IDO expression and expressing or loaded with at least one antigen from a cancer or infectious pathogen may be used as vaccines to promote T cell responses and increase immunity.

Title: Segmentation of 3d medical structures using robust ray propagation
Inventor: COMANICIU DORIN
IPC: G06T5/00
Filed: 2003-03-10
Abstract: A method for segmentation of 3D structures in CT and MR images is provided. The method is based on 3D ray propagation by mean-shift analysis with a smoothness constraint. Ray propagation is used to guide an evolving surface due to its computational efficiency and shape priors are incorporated for robust convergence. The method includes the steps of receiving 3D image data (302); visualizing the 3D image data on a display device (304); selecting a structure in the 3D image data by placing a seed in the structure (306); initializing a plurality of rays from the seed to form a surface (308); determining a speed function of each of the rays (310, 312); evolving the surface by propagating the rays based on the speed function of each of the rays (316); converging the rays on a boundary of the structure (318); and segmenting the structure when all of the rays have converged on the structure's boundary (320).

Title: A valve assembly for opening and closing a fuel line
Inventor: LINDEN SEAN
IPC: F16K31/68
Filed: 2003-06-03
Abstract: The present invention relates to a temperature-sensitive safety valve assembly. The valve assembly comprises a first pressurised fluid region, which region has a first outlet, and a second pressurised fluid region, which region has a heat-sensitive sealing means. A valve between the first and second regions is adapted to be actuated by the pressure of a first pressurised fluid in the first region against biasing means to open the outlet. The heat-sensitive sealing means in the second region fails at high temperature so as to de-pressurise the second region, thereby actuating the valve to move under the biasing means to close the first outlet and seal the first region. The valve assembly comprises a relay unit, which is arranged to sense a parameter, and react to the sensing of the parameter by sealing the first region. The temperature-sensitive safety valve assembly is remotely electronically operable in a wireless manner. Also, the temperature-sensitive safety valve assembly has an electronic device and a solar cell arranged to supply power to the electronic device.
